How too check a Tachometer
Hi, anybody know how I can check a revcounter/tacho to see if it's working. May sound stupid, but they, (two), are on my boat, and are for
petrol engines, but are reading diesel engines through a signal transmitter that uses four black and white segmants on the crank pulley, that
represent the signal from a coil. The signal transmitters are working as they should, but the revcounters don't even twitch. Any help much
appreciated. Cheers Ray
To make a car go faster, just add lightness. Colin Chapman - OR - fit a bigger engine. Chippy

Are they easily removable? If so, can you not test them on a petrol engine on your car?

Some tachometers (mostly older ones) rely on the high voltage pulse from the ignition coil primary to operate.
